Unfortunately in my experience, 90% of events that RP guilds do schedule tend to be in the evenings around the 20:00/21:00 serve time mark due to that being in theory when most people would be online and able to attend cus of college, work, etc etc.
However, I don't think this would be stifling to your progression. Are you more of a morning afternoon player and work evenings or something? Depending on what days and times you are available, I think we have some people who would probably be on at the same time.
For instance myself, I'm (in theory IRL and all that interference) online most of Monday/Tuesday assuming I'm not trying to do some video work, as well as Wednesday/Thursday after 17:00/18:00 server time, depending on trains.
I think I recall seeing others online around these times as well, but can't speak for these people myself.
